Abstract:
As a dielectric ceramic constituting dielectric layers of a laminated ceramic capacitor, a dielectric ceramic is used which contains, as its main constituent, a perovskite-type compound containing Ca and Zr and optionally containing Sr, Ba, and Ti, and further contains Si, Mn, and Al, and when the total content of Zr and Ti is regarded as 100 parts by mol, the total content (100×m) of Ca, Sr, and Ba meets 1.002≦m≦1.100 in terms of parts by mol, the Si content n meets 0.5≦n≦10 in terms of parts by mol, the Mn content u meets 0.5≦u≦10 in terms of parts by mol, and the Al content w meets 0.02≦w≦4 in terms of parts by mol, m and n satisfying −0.4≦100(m−1)−n≦3.9.
